The present invention `appertains to a switch designed to be mounted in a rooml or the like `flush with thefwall and Y,has ifor. its .principal object to providea device rof this natura-which may control the fconneetion of the battery with the -filamentcircuitv n of `a radio,receivingset andthe connection ofthe .A battery with a charger.

Another important Tobject of Atheinven- `'tion is fto .provide awswitch :of this nature which lis convenient temperate, one which @possesses .a simple structure, 4 strong Van-d1 durable, rand Votherwise well adapted to the ,purpose for which yit is'designed. 5 y L i Vi-th the aboveuand-numerous 4other ob- ;jects -in view as Willappearasthe description proceeds, the invention resides-in eer tain e.novel features of construction, and in" the `combination andvwrarrangement {off ,parts as-will be 'hereinafter more fully described and claimed.

c In ,the drawingswitch embodying ythe features of invenwith 4ian elongated :longitudinally extending disposed on the top 3 in Yany suitable manner and are pro.

vided with slots 7 and 8 respectively' registering with slot 4. A bracketv9is mounted arm' of insulatmg 11. AOn each side 12vofvthe easing, interiorly thereof, there is disposed three' eurvedeontacts 13 which are secured in place by terminals 14 extending through the side of the casing and yterminating exteriorly thereof. The series of contacts 13 are alined radially from the ttul-` crum end of the arm 10. rThis arm 10 is pero-` V15p formed of"y sleeves soA that'when ysaid arm 10.A is' swung vided with three contacts` so that contactslengage With` contacts 13 on one side, they will also be engaged, with the other contacts 13 on the other sidev 12.`

V24,y is connected is connected lto the charger. A "nects the charger at its other --Afsecond {series of contacts 16 is mounted onjeach side 12. This second seri-esconsists of two contacts which are radially alined :With-the Afulcrum ofthe arm 10. 1 It will `be seen, that when the arm 10. is

`swungso `that two i ofits Aconta ctss 1' l engage y the contacts 16,011 one side thereof, these contacts 15 Willalso `engage the contacts 16 on the otherside ,12.` The contacts `lo, are Vsimilar to but curved inopposite directions flirom contacts ,131,and" are `securedy in place ofwthecasmg.V y i It isfto benoted that when the arm 1U abuts, the ends 'of the slots 4, 7 and 8 adjacentone end of the casing, thati-ts contacts 15 are in engagement withloontacts 13 and when swung to engage "the ends of the slots 4,7 and Sat the other end ofthe casing, its contacts are in: engagement between conmets 1e, q g t order to understand the advantages of this switch Ithave t,d isclosedan example of its utility `in y3, therparts "being shown diagrammatically. `The radio receiving set isV indicated.41 Vat R [and the leads from the -filament circuit by .numeralsl 2O and 21. These preferably passthrough a plug P and engage --With the `contacts 16 on one side 12 through 'the 'terminals ,117. `The charger is indicated by the letter C 'and the A batter y of 'thestor'age battery,`by Jthe letter A, Wire 22 connects the terminal ofthe A battery with the upper "terminal 14 on'one side 12 of theV casing y 1Afwijref23 connects the positive 4terminal ofthe A battery to the intermediate terminal 14 on thesame side of the casing. One leadyfro'm a source ofl electrical energy as at to the bottom terminal 14 on the same side' out the casing. The other 0F11? f j 1 terminals '17? whichjterminate exteriorly lead 2 5 `from the lsource of electrical energy s wire 26 con-` terminal 27. attached to Vthe bottom terother side of the casing a the positive output termi- This wire 26j-s `minal 14 on the wire29 connects lou nal'28 ,ofthe charger with the terminal 14 y i on vthe `latter mentioned side of the casing While a wirerBO connects the minus output terminal 28 with the top terminal y24 on' its last mentioned side of thecasing.l

It Will thus be seen that Wires 26 .and 29 andl 30y are connected to terminals 14 on the same` sideof the casing asthe leads 20 and 21 are connected to thetermina'ls 17. `A wire 32 liu ment Circuit of the radio receiving set R, thel switch arm 1() is swung so as to be disposed between Contacts 16 whereby the current may flow from the A battery, through wires 23, ywire 33, contacts 16 at the bottom of the casing, lead 21, through the filament, and returned through wire 20, theA upper eontaete 1G, wire 32, and wire 22 to the A battery.

It it is desired. to charge `the A battery, the arm 10 is swung ,into engagement` with contacts 13 thereby Connecting the charger with the power 'line whereby Vthe current may llow from lead 211, through contacts 13 26, through the charger, and returned through wire 2:. 'The Charging or output Current of the charger C'will 'tlow through wire 29, through 4the intermediate contacts 13, through wire 23, through the A battery A, and returned through wire 22, top contacts 13 and the wire 30 to the Chargerv These circuits, of course, have been tollowed merely to illustrate an operative connection which may be used, but it 'is to be understood that numerous other VCircuit arrangements may be used to advantage as will be apparent to thosev skilled in this art.r

.lt is further apparent that lnumerous Changes in the details o't Izonstruetion and :in the combination and arrangement ot' par ts of the switch ma;7 be resorted to without departingr 'from the spirit or'seope of the in vention as hereinafter Claimed, or saeriticingj; any oi'i its advantages. l

Having thus described my invention, what I e'laim as new is Y j ,1. A switch apparatus of the class de scribed including a easing having its upper either ot the aforementioned series' ot con taets.v y I A switeh apparatus of the class de'- seribed ,including a. casing having its upper wall provided -with a slot, an arm pivoted at its lend to the lower wall so as to` extend through the slot, a series of Contacts on each side wall ot' the easing alined betweenv one end olf the slot and the Ltulerum ot the arm, second series of contacts on each side alined with the" other end ot" the slot and at the bottom ot the easing, through wire fulerum of the arm,- spaeed rontaets on the arm adapted to be engaged between either of the atorementioned series ot eontaets, the .tiret mentioned Contactsl being areuately curved and having one end fixed to the easing. y Y Y 3.
